Definitions

  • the rubber-modified thermoplastic styrene resins are not always stable in organic solvents, and particularly when they are used under stress or in the deformation state, their chemical resistance is remarkably reduced in many cases. This has become a bar when the rubber-modified thermoplastic styrene resins have been intended to be utilized in a wider field.
  • the rubber-modified thermoplastic styrene resin used as the (A) component in this invention is a rubber-modified styrene polymer or a mixture of a rubber-­modified styrene polymer with a styrene polymer (unmodified with rubber), in which a rubbery polymer is dispersed in a styrene polymer for the purpose of obtaining high impact resistance.
  • This mixing method may be a simple mechanical blending method; however, in order to obtain a good compatibility, a so-called graft-­ copolymerization method is more perferable in which a styrene monomer and the like are graft-copolymerized in the presence of a rubbery polymer.
  • the above rubber-unmodified styrene polymer includes acrylonitrile-styrene copolymer (AS resin), methyl methacrylate-styrene copolymer, n-butyl acrylate-butylene copolymer, acrylonitrile- ⁇ -methylstyrene copolymer and the like.
  • AS resin acrylonitrile-styrene copolymer
  • AS resin is preferred.
  • the aromatic polyester thus obtained includes polyethylene terephthalate (PET), polybutylene terephthalate (PBT), bisphenol-A isophthalate and the like. Among them, PBT is preferable.
  • the aromatic polyester has an intrinsic viscosity of 1.1-2 dl/g, preferably 1.1-1.5 dl/g and more preferably 1.1-1.4 dl/g, as measured at 25°C in o-chlorophenol (hereinafter referred to as [ ⁇ ] 25°C o-chlorophenol).
  • the intrinsic viscosity falls within this range, the balance of impact resistance and chemical resistance is excellent.
  • the graft copolymer used as the (C) component in this invention is a graft copolymer having a multiphase structure obtained by graft-polymerizing a monomer mixture consisting of 60-80% by weight of an aromatic alkenyl compound and 20-40% by weight of an alkenyl cyanide compound on the main chain copolymer obtained by copolymerizing a monomer mixture consisting essentially of an olefin compound and an epoxy group-­containing unsaturated compund.
  • a silicone lubricant (D) may optionally be contained in the composition consisting of the (A), (B) and (C) components, and in this case, the impact resistance is remarkably increased.
  • the silicone lubricant includes, for example, polydimethylsiloxane, polymethylphenylsiloxane and the like. Polydimethyl­siloxane is preferred, and that having a viscosity of 90-13,000 cP at 23°C is more preferable.
  • the silicone lubricant (D) is added in a proportion of not more than 20,000 ppm, preferably 10-15,000 ppm, more preferably 50-10,000 ppm and most preferably 100-5,000 ppm of the total weight of the (A), (B) and (C) components. When the proportion exceeds 20,000 ppm, the impact resistance becomes inferior.
  • the mixer for producing the thermoplastic resin composition of this invention is not critical; however, there may be used various mixers which are conventionally used for the production of general thermoplastic resins, such as Banbury mixer, Brabender Plastomill, kneader, vented extruder and the like. Among them, vented extruder is preferably used.
  • thermoplastic resin composition Each of the components indicated in the compound­ing recipe of Table 1 was used in the following manner to obtain a thermoplastic resin composition:
  • Example 12 the (B) and (C) components were first kneaded using a single screw extruder at 230°C to obtain pellets, and thereafter, the pellets and the (A) and (E) components were kneaded using a twin screw extruder at 230°C to obtain a thermoplastic resin composition.
